Be it known that we, GEORGE S. EATON and Janus XV. LYON, of Brooklyn, inthe county of Kings and State of New York, have in vented an Improvementin Type-Rubbing Machines, of which the iollowing is a specifi cation.

In this machine for rubbing types the types, as they come from thecasting-machine, are laid upon a bed, passed into a slide, through whichthey are moved progressively and the bases nicked, after which one typeat a time is taken by an oscillating carrienplate and moved betweensmoothing, rubbing, or dressin g cutters or surfaces, and delivered, andthen turned a quarter-rotation and brought back by a secondcarrier-plate between surfaces and cutters, that smooth or rub the typesand remove the burrs at the bases of the letters. Thereby all four sidesof the type-bodies are smoothed or rubbed, the type being rubbed on twoof the sides during the oscillating movement in one direction and on theother two sides during the movement in the other direct-ion.

In the drawings, Figure l is a rear View of the machine. Fig. 2 is anelevation endwise of the shalt. Fig. 3 is a partial plan. at is asection at x is a section at 11 and Fig. 6 is a section ate Fig. 7 is avertical section through the motor-shaft and the oscillating shaft. Fig.Sis a View endwise of the shafts, showing the type-carrying plates. Fig.9 is a rear View of the transfer mechanism, and Fig. 10 is a section ofthe same, and Fig. 11 is arear view representing a modification of thetransfer mechanism. Fig. 12 is a view of thcinner end, and Fig. 13 is adetached plan of the transferbloeh, and Fig. 14 is a separate View ofthe cam A". Fig. 15 is a perspective View of the transfer=block rdetached. Fig. 16 is an end View at the inner end of the same; and Fig.17 is a detached perspective view of the rod u and the jaw at its end,represented on a scale considerably larger than that of Figs. 15 and 16.

The shaft A. is supported by the tubular hearing A upon the upper partof the frame or column B, which column rests upon a suitable table orbench. The shaft A is revolved continuously by abeltand pulley, O, andupon said shaft A there is a cane-wheel, D, having a canrgroove, shownby dotted lines in Fi 2,) into which passes the stud 0 upon the rock-'ing lever E. This lever B has at its lower end an eye for the pivot-bolta, and at its upper end a segmental rack, b, that acts upon the pinion cat the end of the rocker-shaft F. The rocker-shaft F is supported inbearings f, that are upon the adjustable cheek-pieces h h. Thesecheek-pieces h h are provided with tubular supports if If, that surroundthe tubular bearing A A of the motel-shaft A, and there are ai'l'iusting-niits t upon such tubular hearing, by which the cheek-pieces h72 can be moved along upon the said bearings A, and the cheek-pieces aretied together at their up per portions by thebolt 7. and nuts 2 2 at itsends.

Upon the rocker-shaft F there is a stoclgH, upon the sides of which arefastened the inov able carrier-plates I L. The plateI is to be ofathickness slightly less than the width of the types that are to bedressed or rubbed, and the plate L is to be of a thickness slightly lessthan thethickness of the type. These plates IL are changed to suit thefont oft-ypes or the respective letters that-are being rubbed, and thecheekpicces 7L h, being movable, allow for the introduction of thesecarrier-plates and for varying the spaces between the respectivecheck-pieces and the central body-piece, A, that extends up from thetubular bearing A, and in which the stock it of the shaft F oscillateswith such shaft F. It will 110w be understood that the extent ofoscillating motion given to the shaft F, stock H, and carrier- -plates 1and L will depend upon the size of the earn D, which acts upon the studc, lever E, rack Z), and pinion c, and that if the carrier-plates haveto pause at the ends of the reciprocations for receiving or deliveringthe types the portions of the canrgroove that act at these parts of themovement are to be arcs of circles from the center of the motor-shaft,as shown. The types to be rubbed are placed upon the table M, and byhand they are laid down upon their sides and passed in with the 1tionary. It passes through a notch at the edge base end first betweenthe fence on and the guide n, and they are pressed in beneath the plate0 by the reciprocating pusher o,that receives motion from the link 12,lever 3, roller 4, and cam 5upon the cam-wheel D, the spring 6 returningthe pusher to its normal position in line with the fence m. The types asthey lie in'line upon the table and beneath the plate 0 are moved alongprogressively by the pusher 0 as one type after another is introducedbetween the line of types and the pusher.

Upon the shaft F there is a cutter, p, of a widtlradapted to thenotching or nicking of the bases of the types. This cutter is 'moved byand with the rock-shaft F, and it is operative at a time when the lineof types is staof the table and slide, and, if desired,the type that isbeing operated on is held by a cam acting upon a movable section of theplate 0, so

as to keep the type firm while the cutteris removing the central roughportion of the base, where the casting-sprue had been broken off. Thiscutter 12 may be in the form of alever upon the shaft F and be moved atthe proper time by a cam upon the wheel D. rier-plates I L have offsetss s, that are slightly inclined to the radial line and form type-rests,the other portions of the edges of the carrierplates being nearlysemicircles, as seen in Fig. 8, and by dotted lines in Figs. 2 and 10.The parts are so proportioned and timed that the pusher ounoves the lineof types along when the rest 8 of the carrier I is below the end type,and just as the carrier begins to move upwardly; hence the end type iscarried off upon the rest 8, and passes up between the cheek-piece h andthe body A and is kept in proper position by the same, and there arecutters at tthat remove any burrs that may exist at the bases of theletters, or at the angles of the type-bodies, and at the same time thesurfaces of the bodies of the types are smoothed or polished by contactwith the metallic surfaces between which they are carried. I Thetransfer-block r is circular, with a slot in one side. It is placed uponthe arm 1", which arm is pivoted at T2, and the connecting-rod r ispivoted to the arm 1' and provided with a pin, 40, in the grooved-cam A"upon the motorshaft A. This connecting-rod r is kept from dropping bythe jaws of the support A, which is screwed to the tubular support It ofthe cheek-plate h. I The cheek-plate hand body A are notched to allowthe transfer-block r to be moved freely across from one position to Thecarby dotted lines, and is at the side next to the cheek h, instead ofbeing upon the top, as seen by the full lines. that the slot in thetransfer-block is at the top and that it is in line with the openingbetween the body A and cheek-piece h at the time the type-carrier Ibrings over the type; and hence the type is delivered into the slot ofthe transferblock r, and as soon as this takes place the transfer-blockis moved across by the cam A*, link r", and lever r, and receives aquarterrotation, and the type is in a position to be delivered upon thecarrier-plate L as it com the end within the transfer-block, and saidjaw receives within it an ejector-plate, u, having an inclined slot, andthe pin 8 in the jaw of it passes through this slot. A spring, 10,serves to project the end of the rod a, and the lever 10, pivoted at 21,is acted upon by the It is now to be understood projection 31 on thecam-wheel D, and the I broad end 25 of the lever 10 allows the end ofthe rod u to pass beneath it when the transfer-block has been moved intothe position shown by dotted lines in Fig. 9, and at this moment the cam31, acting on the lever w, causes the end 25 to press in the rod u andmove the pin 8 in the inclined slot, and thus project the ejectorlaterally and deliver the type from the slot in the transfer-block uponthe nearly radial surface of the carrier-plate L, by which it is carriedupwardly between the cheek-piece h and the body A, and the projectionsat the sides of the letter-base are removed by the cutters t. Thesecutters are made to shear off the projections perfectly smooth and inline with the sides of the type. This is done with the greatestaccuracy, because the type is kept in its proper position as it restsupon the'carrie'r, and is between the cheek-piece h and the body A". Thetype is carried back upon the table M, where it is laid into a slide orcomposing-stick, H, and there is to be a pusher, 0 that pushes each typeas it is laid down, moving it and the line of types along out of the wayof the next type. This pusher may be actuated in any convenient manner.We have represented by dotted lines the rod 37 below the table M,connecting the pusher 0 to the pusher 0 so that they move together.

In Fig. 11 we have shown a modification of the transfer mechanism bywhich the transferblock is dispensed with. In thiscase a quadrant-slide,38, is provided, into which types are delivered by the carrier-plate I.These are allowed to accummulate until the quadrant-slide is entirelyfull, and this is to be proportioned in such a manner, according to thethickness of the types, that when one type is added by the carrier-plateat one end of the quadrant-slide another type at the other end of theline of types is in position'to be taken off by the other type-carrieras the carriers are oscillated the other way.

It will be apparent that the types are presented to the second carrier,L, with the bodies in position for the two unrubbed sides to be actedupon by the cutters t.

It will be apparent that the cheek-pieces having the tubular supports hit upon the tubular bearings of the rocker-shaft, the sur faces of thecheek-pieces can be turned or ground off in a lathe with the greatestaccuracy, and they will always occupy a plane that is perpendicular tothe axis of the oscillating shaft; hence there is no risk of the partsbecoming inaccurate when adjusted, and the bodies of the types asdressed will always be perfectly parallel, and risk of inaccuracy inadjusting the parts is prevented. The sur faces of the cheek-pieces andbody with which the types come into contact are subject to wear. Theymay therefore be of chilled iron and ground off with great accuracy; orthey may he made with movable plates of steel or other suitable metalthat can be changed from time to time, as necessary. In cases where thebases of the letters overhang at opposite sides of the types, and thesebases are to remain-as in scri pt lettersthe faces of the cheek-piecesand body are to be grooved concentrically to allow these bases to passthrough the machine. If only two sides of the type body are to bedressed, it will only be necessary to pass the types through between thebody and the cheekplate 7L and deliver them upon a suitable rule orholder.
